Oh, I see, the curl is what I was missing. Thanks, that helped a lot.

http://imgur.com/KzXQADm Here's my poor limited understanding of em waves without using vector calculus (I've heard of "curl" or "divergence", but don't really know what they are). So my question is that two rectangles have different directions of integration. For example, for the top graph...

I've seen derivations for c=E/B and c=1/√μ0ε0, but I don't seem to get the directions right. i.e. I end up with a negative sign in one of the equations. The derivations I've seen do not use vector calculus. One derivation I've seen is in http://Derivation[/PLAIN] of Electromagnetic Waves from...
